Title: Can anyone ID this National Receiver
Post by: N4LTA on January 02, 2022, 05:42:53 PM
Anyone ID this receiver. Looks like a VHF of some type. Looks a little like  HFS but has a magic eye tube.

I found it . It is a NC 108 FM receiver/tuner. Not much use as far as I can tell. Not even for parts. Maybe as a box and power supply for something homebrew.

I wondered if that was the case. The case is in pretty decent shape for repainting.

I couldn't agree more.  Just looking at that ancient shell of a radio makes me want to adopt it and do a restoration.   ;D

It's not that uncommon. Over the years, I've received requests for the manual for this receiver. FM Receiver (it's not a tuner) covers 86 to 110 MHz. It's mono and it has a 6V6GT audio output stage.

They made two versions; the table version which you have with the electric eye tube and a rack version in black that has a milliammeter in place of the electric eye tube. Both versions are shown the schematic.

Manual has alignment procedure, parts list, operating info, and addenda to describe the "De-Emphasis" switch mounted on the chassis along with some other info. The receiver also has a pair of external terminals after the first audio tube to drive an external amplifier (for that "big boy" wall-to-wall sound).

I had one of those a few years ago.  It worked just fine, with decent fidelity on FM, but did drift a bit.

Absolutely worth restoring from the days of mono FM, just after the re-allocating by the FCC.
